Police are on the lookout after a spate of flashings in and near Teddington Lock.

At about 5pm on January 31 a man exposed himself to two girls near Beaufort Court. The girls fled.

Three days later, just after 7.30am, a man flashed at a 19-year-old woman.

The police received three similar calls before that – on June 16, December 9 and December 30.

On each occasion, victims were not touched by the perpetrator, who has always been described as a white man. Police have given no further description of the suspect or suspects.

"Our officers will be on patrol in Teddington Lock area to reassure members of the community - if you have any concerns please speak to one of the officers or call police on 101.”
